The stress state of a plastic layer with a variable yield strength under a flat deformation

Abstract

We study the stress state of a plastic layer with a variable yield strength in a strip under a flat deformation with a tensile load. We approximately calculate the first integrals of the system of plastic equilibrium equations, obtain an analog of the first Hencky theorem, and solve the conjugation problem for stresses on the contact boundary. © 2013 Allerton Press, Inc.
